0 a/ZZ whom it may concern,.-

Be it known that I, JOHN C. KEARNS, a citizen of the United States, residing at Maitland, in the county of Mifin and State of Pennsylvania, have invented certain new and useful Improvements in Chain -Pumps; and I do declare the following to be a full, clear, and l exact description of the invention7 such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the acccompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specication.

My invention relates to water-elevators; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims.

The invention belongs to that class of water-elevators in which an endless chain having cups or buckets is employed, and the essential features are fully illustrated in the aecompanying drawings, which form a part of this specification, and in which- Figure l is an elevation of the overground structure, broken away to show the arrangement of windlass, chain, and buckets Fig. 2, a horizontal section through the line y y of Fig. l, and Fig. 3, a detail showing the construction of the links which form the body ofA the chain.

Referring to the drawings, in which similar letters of reference indicate'like parts in all the figures, A represents the' above-ground structure, to which is secured a spout or way, A', and in which is properly journaled the shaft B ofthe sprocket-drum or windlass B.

C designates the links of the endless chain, which passes over the drum B, and each link is provided with a cup or bucket, D. These links C are cut from a single piece of sheet metal, and are formed with a part, c', projecting in one direction, and a wider portion, c'j, cut away at c3. The part c is of a width to allow it to fit snugly in the recess c3, and the parts e2 project laterally to engage the teeth or sprockets of the drum B. Both the parts c and c2 are rolled'inwardly transversely to the tity of water.

'e line of the chain and engage around bars c, as

shown, the part c operating in the recess c3 of the part c2 of the preceding link, and the part cZ forming the recess for the succeeding link, as well as sprocket-'engaging projections. Upon each of these links is secured a peculiar bucket, D. `These buckets, owing to their reversed positions when in service, must be of such form and construction as to carry a maximum quantity of water on their upward traverse, to have a spout which will directthe water clearly and fairly into the trough A without waste, and whichshall be so arranged obliquely to the vertical line of the chain that they will avoid touching the-trough in their passage and lap one another, as shown. To these ends the frames of the buckets are arranged' at an angle of approximately fifty degrecs from the vertical plane of the chain, and each is formed with a long side, d, which forms the spout, and a short side having a lip, d. This lip stands nearly vertical when the bucket is on the upward traverse,and is of importance in assisting the bucket to hold a larger quan- In the construction and arrangement of these links and bucketsV lie the gist of this invention.

Having thus described the invention, what I claim, and desire to secure by Letters Patent, 1s

l. In a water-elevator, the endless chain, formed of links C, cut from a single piece of sheet metal to form a part or tongue, c, anda wide portion, ci, having a recess, ci, combined with the transverse bars c an d adapted to serve in series, as set forth. 1

2. The buckets D, secured to the links C and lapping one another, as described, and pro-A vided with spout d and lip d', the said buckets being secured to the links at an angle, and adapted to serve as and for the vpurposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
